STOP MECHANISM FOR SPINNING-FRAMES, SPEEDERS, AND THE LIKE.

Application filed October 28, 1912.

To all whom it may concern Be it known that I, EARNEST L. JACKSON, acitizen of the United States, residing at Columbus, in the county ofMuskogee and State of Georgia, have invented certain new and usefulImprovements in Stop Mechanisms for Spinning-Frames, Speeders, and thelike; and I do hereby declare the following to be a full, clear, andexact descriptiorf of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to stop mechanisms for spinning frames, Speeders,and the like, and has for an object to provide a device adapted toactuate the usual and ordinary stopping mechanism on a speeder when thecone belt breaks.

A further object of the invention is to provide mechanism which inaddition to stopping the speeder when the cone belt breaks also servesto actuate the stopping mechanism when the traverse runs too high or toolow.

A further object of the invention is to provide mechanism which willactuate the stopping device of a spinning frame when the traverse runstoo high or too low.

A further object of the invention is to provide a mechanism having arack and pinion such rack being connected with the traverse and movingtherewith and with a trigger serving to hold a weight suspended,whichwhen dropped will serve to actuate the stopping mechanisms of thespeeder or spinning frame.

With these and other objects in view the invention consists in theconstruction, combination and arrangement of parts as will behereinafter more fully described, illustrated .in the accompanyingdrawings, and pointed out in the claims hereunto appended. I j

Fig. 3 is anenlarged view'in side elevation of the device seen from the sideindicated at Fig. 1. Fig. 4 is a view of the device in side elevationfrom the side opposite that seen at Figs. 1 and 2.

. The improved ,stoppingmechanism which forms the subject matterv ofthis. application cone 22 of a speeder or beneath the traverse 23 of aspinning frame. Upon the frame 20 a sliding frame 24 is mounted, thesaid frame carrying an arm 25 connected by means of a link 26 and bellcrank lever 27 and through the medium of a rod 28 with the usual andordinary latch 29, as shown in" Fig. 1 and employed upon speeders or tothe belt shifting device indicated at 30 upon the spinning frame shownat Fig. 2. It will be therefore, apparent that when the sliding frame 24drops, it will, through the medium of the mechanism just enumerated,actuate the latch of a speeder or the belt shifting device of thespinning frame to stop the machine in the usual well-known manner.

To insure the dropping of the sliding frame 24 when the cone belt 31breaks, the cone drop 32 is provided with a rod 33, and the slidingframe 24 is connected with such drop through the medium of a rod 34slidably connected with the sliding frame by means of a reduced neck 35and head 36 and clip 37, as indicated more particularly at Fig. 11.When, therefore, the cone belt 31 breaks and the lower cone drops, therod 34 actuates the sliding frame 24 and through the medium of the bellcrank lever 27 and the connecting means, the stopping mechanism of themachine is actuated.

For actuating the stopping mechanism by the traverse of the speeder, orwhen the spinning frame runs beyond its limit, a rack 38 is slidablymounted upon the frame and engages with a pinion 39 rigidly mounted upona shaft 40, which shaft also carries a crank disk 41. The crank diskcarries a wrist pin 42 positioned to engage in a notch 43 in theupstanding arm 44 of the latch member 45, shown in perspective at Fig.14. The rack 38 is also provided with a pintle 46, positioned to engageunder the end of the latch member 45 opposite the arm 44.

From the foregoing it will be apparent that when the wrist pin 42engages the notch 43 in the latch 45, it serves to depress the same andwhen the pintle 46 engagesthe opposite end of such latch it serves toraise such opposite end and to have the same ef fect upon the latch asbeing" depressed by the wrist pin 42. It will, therefore, be apparentthat' whether the rack 38 runs too high or too low, the latch 45 will besimilarly actuated. The latch 45 is provided with a detent 47 whichserves to engage the lever 48 and to hold such lever 48 against thetension of the spring 49, the spring 50 tending to hold the latch 45against depression by the wrist pin 42 or the pintle 46. The lever 48 ispivoted at 51 upon the stud carrying the spring 49, and is actuated bymeans of a lever 52 pivoted to the frame as at 53 and provided with acam extremity 54 against which acts a roller 55 carried by an arm 56formed upon or moving with the link 26, so that when the frame 24 dropscarrying with it the link 26, the roller 55 acting" against the camsurface 54 servesto throw the lever 52 in a direction indicated by thearrowin Fig. 7 and to throw therewith, through the mediumof the link 57,the lever 48. The lever 48 bears against the lower end of the trigger 58pivoted at 59 to the frame 20 and held, normally yieldingly against theaction of the lever 48, by means of a spring 60.

Slidable upon the frame 20 is a weighted drop 61 having a notch 62positioned to be engaged by the trigger 58, when held in position by thelever 48 and to hold such weighted drop in elevated position. Theweighted drop is provided with a slot 63 embracing the arm 25 and isprovided with a pin 64 positioned to impinge against such arm when theweighted drop falls, so that when the trigger 58 is released from thenotch 62,, the weighted drop falls and the pin 64 impinges against thearm 25 by reason of the weight of such weighted drop 61 serving to movethe frame 24 downwardly and to actuate the bell crank lever 27 and rod28 as described in relation to the drop of the cone, such drop of theframe 24 being permitted by the elongated reduced shaft 33 of the link34 connecting the same to the cone drop. It will be apparent,therefore,that as the traverse runs too high or too low moving the rack 38therewith, the shaft 40 will be rotated to actuate the latch 45 eitherthrough the medium of the wrist pin 42 or the pintle 46,, whereby thedetent 47 is depressed out of engagement with the lever 48 which permitsthe spring 49 to throw such lever and also permits the spring to throwthe trigger 58 out of engagement with the notch 62. This permits theweight of the drop 61 to fall to actuate the sliding frame 24 and bellcrank lever 27 as described. It will be apparent therefore, that as thetraverse either of the spinning frame or the speeder runs above or belowits normal limit, the stopping mechanism of the machine will beactuated. It will also be apparent that as the sliding frame 24 drops itwill through the medium of the lever 52 return the parts to engagingposition, so that when the weighted drop 61 is again raised, it will beautomatically engaged by the trigger 58 to hold it in normal position.To raise the weighted drop 61 the said drop is provided with an offset65 having a recess 66 proportioned to receive the extremity of the bellcrank lever 67 pivoted at 68 to the frame 20 and controlled through the1116- di'umof a rod 69 with a lever 70 pivoted in the creel 71 of thespeeder or the lever 7 O pivoted to the frame of the spinning frame. Inthe speeder the lever 70 is connected with the sliding rod 72 which ismanually oper- 9 ated to start the machine after being automaticallystopped. It will be understood that the rod 72 runs the entire length ofthe speeder and is controlled from any point at which the operator-maybe. This rod 72 is found upon all speeders and the lever 70 is simplyconnected therewith in any usual well-known manner. It will be apparenttherefore, that when the trouble has been adjusted and the rod 72manually moved to start the machine, the moving of such rod 72'automatically raises the weighted drop 61 and sets the machine inposition for use.

To connect the traverse 73 of the speeder with the rack 38 an arm 74 isrigidly connected therewith, as shown at Fig. 1,. and is connected withthe rack in any approved manner as indicated at Fig. 3. To connect therack with the traverse of the spinning frame a rod 76 is connected withthe traverse 23 and any approved coupling as 77 is employed to connectwith the upper extending rod 78, which forms a continuation. of the rack38.
